The 49ers did not draft a quarterback for the second time in three years, but they’ve apparently found one in Kory Faulkner, who went undrafted out of Southern Illinois.

“Just got off phone with Coach Harbaugh!! I am a 49er!!!!!!!” Faulkner tweeted shortly after the draft ended.

The 49ers only had room for four undrafted free agents as a result of their 12-man draft class and Friday’s trade for wideout Stevie Johnson. Also signing were Stanford linebacker Shane Skov, USC outside linebacker Morgan Breslin (a Bay Area product), Miami tight end Asante Cleveland (who went to Christian Brothers High-Sacramento), safety/returner L.J. McCray from Catawba College (Salisbury, N.C.), New Mexico center Dillon Farrell and Michigan State offensive tackle Fou Fonoti.

Faulkner (6-foot-4, 227 pounds) had 18 touchdown passes and just four interceptions last season as he capped his third season as the Salukis’ starter.

Skov reportedly drew the Raiders’ interest before signing with the 49ers, reuniting him with defensive coordinator Vic Fangio and coach Jim Harbaugh.

“Don’t know where the whole Oakland thing came from… But I’m headed to the 49ers, gunna make my mark in this league before it’s all over,” Skov tweeted.

Asked if Skov signed, general manager Trent Baalke could not immediately confirm, noting that others in the personnel department were finalizing deals upstairs during his press conference.

Outside linebacker Morgan Breslin, a Bay Area product who attended USC, also apparently came to terms with the 49ers. He attended Las Lomas High-Walnut Creek and Diablo Valley College before transferring.

Breslin had five sacks last season before undergoing hip surgery. In 2012, he led USC with 13 sacks and made All-Pac-12 second team.

Safety/returner L.J. McCray hails from Catawaba College, which is also the alma mater of 49ers defensive line coach Jim Tomsula. McCray (6-foot-1) missed most of the 2011 season to injury. He averaged 22.7 yards on 21 kickoff returns last season.
